But there doesn't appear to be an installer for anything other than the Outlook plugin. I downloaded the zip file, and there's a bunch of files that I don't know what to do with.

I think I may try PopFile instead. It's got an installer and very clear instructions. I'm sure I could get the other thing working, but the instructions on that page are either not clear, or the ones I need are mixed in with the overall FAQ. I'm not fond of that.

Thanks for the link, Tony (again, I remember you posting it before, but I'll give it a shot this time ).
